permitting. the

stem'38 from which rojects an arm 39, and this arm is connected to a rod40 by means of a link 41. The rod 40 is. connected to a plunger 42arranged within a cylinder '43 that communicates withthe storagereservoir 15, and the end of the plun er is constantly exposed to thepressure of uid in the reservoir. Around the rod 40 is coiled a spring48 that tends normally to force the p unger or piston inward against theressure of the gases. Projectin from the p unger is a pointer 49 thatextends through a suitable slot formed in the cylinder 43 and may moveover graduations for the purpose of indicatingthe pressure in thereservoir. 7 hen the pressure is abnormallyhigh, the plunger 42 ismoved-outward, and this movement is transmitted through the previouslydescribed connections to the valve 36, turning the latter to present aport of smaller area into feed position, and the greater the pressure,the smaller .the port, or if the pressure is exceedingly high, the valvemay be moved to closed position. In this manner the quality of theexplosive compound is governed in accordance with the degree of pressurecontained within the reservoir.

Projecting from one end of the valve 24 is a stem 40 carryin an arm 41which may be connected by am 42 to the stem of plun er 26, and mountedalso on the stem 40 is a c etent disk 48 havin a tooth 49 that isarranged to be engage by a pawl 50 pivoted on the'frame and moved by aspring 51 in the direction of the disk, so that the pawl will moveintoengagement with the tooth 49. When, therefore, the plunger 26 is movedoutward, the movement is transmitted through the connections to thevalve 24, and the latter will be turned until its )Oll) is in verticalposition in alinement wit the oil feed pipe 33 and the ort will befilled with oil, asolene or the li e. Connected to the paw 50 is an arm53 that is arranged in the path of movement of a lug 54 rojectin fromthe face of the rod 42, and w en the p unger has nearly completed itsstroke, the lug 42" will engage the arm 53 and will move the pawl fromengagement with the tooth 49' inorder to permit the return of the valve23 to such position as to place its port in communication with the pumpcylinder, and the passage Way 22. To accomplish this latter movement thestem of the valve is connect-ed at one end to a spring 58, said springbeing suitably set-ured to a fixed point and being placed under stressduring the outwardmovement. of the plunger, so that as soon as the pawl50 is released, the spring is free to contract and move the valve 23 toa position to effect discharge of the contents of the port into the exlosion chamber.

Duringt e in stroke of the plun er 26 the air previously drawn into thecylin er is compressed, and during the latter portion of the stroke, thevalve is moved to the. 0 en position, so that the compressed air strikithe hydro-carbon will force the latter through into the explosionchamber and form an explosive compound which is ignited after passmginto said chamber. The ignition is accomplished at the proper time bytheengagement of theend of arm 60 of the rod 42 with the movable arm 61of a sparking plug 62 so that the circuit will be broken for-the purposeof creating a spark and firing the cha e. a

This charge instantly passes beyond t e valve 21 into ,the storagereservoir. At suitable points onthe frame are bearingsfor the support ofa shaft that is provided with a crank 81 connected by rod 28 to thelunger26.

The exhaust gases pass throng the pipe 90 to a vertically disposed flue104 that extends upward from a casing 105 surrounding the explosionchamber, and as this flue is heated by the exhaust gases, an upwarddraft is created which wil draw in the cool outer air, so that acirculation may be main-' working space of the engine, owing to the factthat in the latter case the operation is 'intermittent and exertsconsiderable strain on the working parts, while the use of a continuousvolume of' gas of practically uniform pressure permits smooth runningofthe engine at uniform speed.
